how to reset speedometer on a 2001 GM suburban LT after replacing instrument cluster.

 

Welcome to the forum.

Someone here may be able to answer your question. Might have to go to a dealer tho.

 

Can you define 'reset'? is it showing the MPH, but it's off, or it doesn't show anything?

 

IT does not work at all replaced the cluster and speed sensor and still doesn't work>????

 

assuming you have a new cluster/ it will have to be programmed by the dealer.
here is the great part. if you install it and drive it over a set amount, the cluster with lock out and have to be sent back to unlock it. This will cost you $ so don't let it lock out
